Rayshon Young, 39, psychologically and physically tortured the victim — whom he met when she was 17 years old — to turn her into a sex slave.

A pimp who forced a woman into prostitution for nearly a decade will spend up to 15 years behind bars for sex trafficking, Manhattan prosecutors said Thursday.

Rayshon Young, 39, psychologically and physically tortured the victim — whom he met when she was 17 years old — to turn her into a sex slave.

From November 2007 to October 2014, Young took all of the victim’s earnings and pummeled her when she didn’t bring in enough cash or if she broke his rules, according to the Manhattan district attorney.

“For years, Rayshon Young controlled this young woman’s every waking moment by keeping her in constant fear for her life,” DA Cy Vance Jr. said in a statement.
